江苏今年首个500千伏电网重点工程投运 全力保障“迎峰度冬”

Core Viewpoint - The successful operation of the Jiangsu 500 kV power grid project marks a significant advancement in the province's energy infrastructure, supporting stable electricity supply during peak winter demand and aligning with the "14th Five-Year Plan" for energy development [1][3]. Group 1: Project Details - The Guodian Investment Binhai 2×100 MW unit expansion project is located in Yancheng Binhai Port area and is a key project in Jiangsu's energy strategy [1]. - The expansion includes two 100 MW coal-fired power generation units, expected to generate an annual output of 10 billion kWh, sufficient to meet the annual electricity needs of approximately 4 million households [1]. - The newly constructed transmission line spans 89.045 kilometers, enhancing regional electricity supply capacity and supporting the efficient integration of renewable energy sources [3]. Group 2: Engineering Challenges and Innovations - The project faced complex geological conditions and required coordination across multiple infrastructures, including highways and railways, leading to high construction risks [4]. - Innovative use of drones for precise surveying and the development of tailored plans for each crossing were implemented to ensure efficient construction within limited operational windows [4]. Group 3: Broader Energy Context - Since 2025, Jiangsu has been advancing both traditional industry upgrades and new industry developments, resulting in stable growth in electricity demand [5]. - The construction of additional 500 kV transmission projects, such as those at Jiangsu Guoxin and Jiangyin Ligang power plants, has strengthened the grid's capacity to integrate large coal-fired power units and enhance system regulation capabilities [5]. - Other major network projects, including Huaneng Tongzhou Bay and Yancheng Gaorong 500 kV substations, are under construction to further optimize the electricity grid's capacity for renewable energy integration and overall supply capability [6].
